Filed: 1988-09-14
Abstract: PURPOSE:To activate reactive gas and to enable high-speed film formation by inducing electron beams caused from a hollow cathode provided between a moving long size material and a hearth with a focusing coil and generating high-density plasma in the vicinity of the long size material. CONSTITUTION:Substance (e.g., Ti) 20 to be evaporated is held in a hearth 12 in a treatment chamber 1 and reactive gas (e.g., N2) is introduced thereinto through a gas introducing pipe 11. Then positive voltage is impressed to the hearth 12 and also negative voltage is impressed to a long size material 3 and a hollow cathode 13 provided between the long size material 3 and the hearth 12 is actuated. The above-mentioned Ti 20 is melted by electron beams 14 caused from the hollow cathode and evaporated into the reactive gas. Further electron beams 17 are induced by a focusing coil 16 provided around the hollow cathode 13 and plasma is formed in the vicinity of the long size material 3. Thereby N2 is activated and a TiN thin film smooth and excellent in adhesion is obtained at high velocity.

Abstract: PURPOSE:To protect the entire circuitry and to detect abnormality indirectly based on disablement of load circuit by connecting a load and a power-factor improvement capacitor in parallel and connecting a protector such as a temperature fuse in series with the power-factor improving capacitor thereby interrupting the load circuit upon occurrence of abnormality. CONSTITUTION:A protector 4, i.e., a temperature fuse, and a power-factor improving capacitor 3 are connected in series in a capacitor body 5. Terminal 6a is connected through a power source line L1 with a power source terminal a1 and a terminal 6b is connected through a power source line L2 with a power source terminal a2. Terminal 7 is connected to the joint A of the protector 4 and the power-factor improving capacitor 3, and one end of a load 2 is connected thereto. Upon occurrence of abnormality, the protector 4 functions and the fuse is blown thus interrupting the capacitor circuit and further interrupting the load circuit. Consequently, safety of entire system can be ensured. When the load 2 comprises a fluorescent light, the fluorescent light does not light and the abnormality can be detected easily.

Title: Speaker unit
Inventor: TAKAHASHI SHIYUNICHI
IPC: H04R9/02
Filed: 1983-12-03
Abstract: PURPOSE:To decrease the three-dimensional high frequency distortion and to obtain a speaker unit with the low distortion by providing a voice coil with larger winding width than the width of a magnetic gap, and by setting the driving force constant in spite of the dislocation of the voice coil. CONSTITUTION:A center pole 1B of a pole yoke 1 has the height which is more than the upper limit in the up and down oscillation range of the upper end of a voice coil 5, and taper faces 13 and 13 are formed at the center pole 1B. These taper faces 13 and 13 constitute a magnetic-flux density setting means which makes the value of a force factor B.l constant within the oscillation of the voice coil 5 at least, and thus, the magnetic-flux density distribution in an opposite part 12 of the center pole 1B and the taper faces 13 and 13 becomes the step state. Thus, even if the voice coil 5 has the dislocation, the total magnetic flux which intersects with the coil 5 does not change. Therefore, the value of the force factor B.l becomes constant within the amplitude of the coil 5, and the driving force which operates the coil 5 also become constant. As a result, the driving force of a sine wave is obtained for the sine wave current.
